Round-up of 74 laptop power adapters: original or universal?

Are original adapters better?


Test results

Below you have all the charts with the results that were referred to in the text. Adapters from notebook manufacturers are marked in red, universal adapters up to 80 watts are blue, from 90 to 95 watts are green, and 100 watts and higher are black. We picked two charts in which all 74 adapters appear, it's the 60 watt test where we measured both efficiency and the ripple.
